Problems solved by technology

The problem existing in the existing identification methods of garbage and other pollutants is: simply using the gray value information of the image, without processing the information such as the color, tone and brightness of the image, a large amount of valid data is lost, and the identification of garbage and other pollutants is difficult. less effective

Embodiment Construction

[0051] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0052] refer to figure 1 , an intelligent road sweeper of the present invention, comprising: a road sweeper body, a laser radar 1, a camera 2, an encoder 3, a dust concentration detector 5, an inertial sensor 6, a GPS7 system and a processing controller.

[0053] LiDAR 1: Installed on the roof of the road sweeper, it is used to perform 360° rotating scanning of the environmental information around the vehicle, and obtain point cloud data of surrounding objects, especially the shape of the front and rear vehicles and pedestrians of the road sweeper Size, movement speed and distance information from the vehicle, identify curbstones on both sides of the road and the distance between the road sweeper and the curbstone and other information. The camera 2 forms a binocular camera form: it is installed on the top of the vehicle, and two cam...

Abstract

The invention discloses an intelligent road sweeper and its road pollutant identification method and control method. The road sweeper includes: a road sweeper body, a laser radar, a camera, an encoder, a dust concentration detector, an inertial sensor, and a GPS system and handle the controller. The road pollutant identification method includes: obtaining the RGB image of the clean road surface and road facilities to be cleaned, converting the acquired RGB image into HSV space, and obtaining a BP neural network model that can identify the clean road surface and road facilities; The real-time image information of the road is input to the BP neural network model to identify pollutants. The method for identifying pollutants such as garbage in the present invention utilizes the HSV feature of the road image, which has a larger amount of information than the gray value of the image alone, and the effect of identifying pollutants such as garbage is better.

Description

technical field [0001] The invention belongs to the technical field of sanitation machinery, and in particular relates to an intelligent road sweeper and its identification method and control method for road pollutants. Background technique [0002] Road sweeper is playing an increasingly important role as a commonly used sanitation equipment, but the current road sweeping operation is still based on the road sweeper that requires driving control. The existing garbage and other pollutant recognition technologies of road sweepers mostly use image recognition methods, and the existing image recognition and image feature extraction are mostly based on the pixel gray value, gray gradient and edge shape features of the image. Through the template matching method, that is, by comparing the real-time collected road image with the preset standard clean road image template, the pollutant areas such as garbage are extracted. The problem existing in the existing identification methods...
